config CLKDEV_LOOKUP bool select HAVE_CLK config HAVE_CLK_PREPARE bool config HAVE_MACH_CLKDEV bool config COMMON_CLK bool select HAVE_CLK_PREPARE ---help--- The common clock framework is a single definition of struct clk, useful across many platforms, as well as an implementation of the clock API in include/linux/clk.h. Architectures utilizing the common struct clk should select this option. menu "Common Clock Framework" depends on COMMON_CLK config COMMON_CLK_DISABLE_UNUSED bool "Disabled unused clocks at boot" depends on COMMON_CLK ---help--- Traverses the entire clock tree and disables any clocks that are enabled in hardware but have not been enabled by any device drivers. This saves power and keeps the software model of the clock in line with reality. If in doubt, say "N". config COMMON_CLK_DEBUG bool "DebugFS representation of clock tree" depends on COMMON_CLK select DEBUG_FS ---help--- Creates a directory hierchy in debugfs for visualizing the clk tree structure. Each directory contains read-only members that export information specific to that clk node: clk_rate, clk_flags, clk_prepare_count, clk_enable_count & clk_notifier_count. endmenu
